Background: It is a common understanding that exercise benefits human health in many aspects. For example:
1. Exercise improves mood.2. Exercise combats chronic diseases.3. Exercise helps manage body weight.4. Exercise strengthens heart and lungs.5. Exercise promotes better sleep.6. Exercise can increase reproductive behavior.
Objectives: To determine if long term voluntary exercise would benefit mood
Design: Voluntary exercise10 wks
from age 25 days
Swim test 15 min

FMRI Evaluation of Chemobrain
What is Chemobrain ?• Overall reduction in cognitive performance: primarily in attention, concentration , information
processing speed and memory• Self report and confirmed by neurobehavioral testing• Dramatic negative impact on QUALITY OF LIFE. Compromises daily functioning at home, job and
socially
Study Objective :• Develop fMRI methodology to identify neuronal substrate affected by chemotherapy• Same fMRI methodology can then be used to longitudinally evaluate efficacy of interventional
therapies developed to address the chemotherapy induced cognitive deficits.
FMRI Study : • Interrogate functional networks supporting working memory and attention Stroop Task N-back Task ( 1 and 2 back )

He could easily be doing this in an MRI
Advantages of the Standard Video Game Platform for fMRI
• Hundreds of millions of potential subjects already trained by Nintendo, Microsoft, & Sony
• Games are more fun – better tolerance & engagement of subjects in more complex tasks
– Tools and expertise for development now widespread– VR Labs and game design curricula at many
universities• CWRU Virtual Worlds Laboratory
– Leads to much faster development cycle• Controller and first task developed in 6 months!

Our Take on the MindBrain Issue• Brains become minds through bonding,
attachment, learning, a ‘holding environment’• A person needs a facilitating environment so as to
allow a coordinated mind to emerge from a brain• Early attachment patterns predict later personality
development, adaptation, and psychopathology• Our translational model allows us to tie together a
neurobiology of sociality and to understand psychotherapy, as well as other ‘biological’ interventions, in this context
And so we study
• Neuropeptide ‘operators’ in bonding and separation distress
• Our favorites are oxytocin and the endogenous opioid system
• We have studies going with humans and also prairie voles, the latter a very social mammal which mates for life. Rat’s aren’t very social, and may not be the best model for studying anxiety and depression, if you assume, with humans, that a Self cannot develop without an Other
Studies completed or in process
• 1. fMRI study with with ‘depressed’ prairie voles inhaling oxytocin
• 2. pairs of psychologists and psychiatrists inhaling oxytocin and reporting on changes in experience
• 3. using a partially synthetic opioid in treatment refractory depression
• 4. fMRI study of mildly depressed people, treated with oxytocin to see if they become more ‘connected’ and ‘involved’
